电动力学观点下的高中物理电磁学典型问题研究

RESEARCH ON THE TYPICAL PROBLEMS OF PHYSICAL ELECTROMAGNETICS IN SENIOR HIGH SCHOOL FROM THE VIEWPOINT OF ELECTRODYNAMICS

当前中学物理教学对教师的知识结构提出了新的挑战,而物理学科本体知识又是影响物理教师教学能力的关键因素之一。物理学科本体知识的水平决定着教师的物理观念,从而影响着教师物理教学行为的选择和调控。因此,物理教师要尽可能地站在高观点下(即大学电动力学角度)审视中学物理的内容,加强挖掘中学物理问题背后隐藏的知识,从而提高自己的物理素养,形成全面、扎实、灵活的学科知识结构。本文将结合在教学中遇到的具体问题,浅谈如何在电动力学观点下对高中物理电磁学问题进行深入研究。

Nowadays,physics teaching in senior middle school has posed a new challenge to teachers.Physics subject ontology knowledge is one of the factors affecting physics teachers'teaching ability.The level of ontological knowledge of physics subject determines teachers'physical concepts,thus affecting the choice and control of teachers'physical teaching behavior.Therefore,physics teachers should examine the contents of middle school physics from a high point of view(i.e.university electrodynamics)as far as possible,strengthen the excavation of hidden knowledge behind middle school physics problems,so as to improve their physical literacy and form a comprehensive,solid and flexible subject knowledge structure.In this paper,combined with the specific problems encountered in teaching,the author gives a brief talk about how to do in-depth study of high school physical electromagnetism from the viewpoint of electrodynamics.
